我有一个使用 create-react-app 引导的 React 应用程序。该应用程序运行在docker容器中，并已部署在子域中。假设域名是 http://mycompany.com ，那么我的 React 应用程序位于 http://mycompany.com/users/userid/apps/reactapp 。

有一个反向代理服务器可以进行 URL 重写，将基本 URL 更改为子域 URL。这就是我的 package.json 的样子 -

{
  "name": "my-app",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@material-ui/core": "^4.12.4",
    "@testing-library/jest-dom": "^5.16.1",
    "@testing-library/react": "^12.1.2",

    "typescript": "^4.5.4",
    "web-vitals": "^2.1.2"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": [
      "react-app",
      "react-app/jest"
    ]
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  },
  "devDependencies": {
    "css-flatten": "^1.0.1",
    "react-hot-loader": "^4.13.1",
    "react-select": "^5.4.0",
    "sass": "^1.45.2"
  }
}

我面临的问题是，即使在我使用react-scripts start重新启动开发服务器后，任何JS文件更改都不会得到反映。仅当我重新启动 docker 容器时才会反映出来。在浏览器中，我检查过，bundle.js 文件没有最新的更改。我已经尝试过这些事情 -

1. 删除node_modules/.cache、node_modeules
2. 在react-scripts启动中使用CHOKIDAR_USEPOLLING=true

我可以在开发服务器日志中看到，正在检测到文件更改，但这些更改并不用于提供给浏览器。即使我删除了一个文件（因此我可以在开发服务器日志中看到错误日志），但即使浏览器刷新，应用程序仍然没有任何更改。
